年产量40万吨高速线材车间设计
摘要
根据设计要求拟建一个优碳年产40万吨的高速线材生产车间它的最高轧制速度为120ms保证速度为100ms产品规格为φ55φ12mm盘卷单重约2吨
连铸坯在步进梁式加热炉中使用煤气加热侧进侧出加热能力为75th加热炉由微机控制出炉温度为900℃~1050℃
该套轧机采用全连轧无扭工艺连铸坯为120×120mm长约为12m单重约为13t的方坯在12架平立-交替布置的粗轧机和中轧机之后布置了4架预精轧机8架精轧机4架的减定径机组
轧后冷却通过水冷箱和一套斯太尔摩冷却运输线120m来完成该套斯太尔摩冷却运输系统采用延迟型冷却装置可对成品轧材的最终性能控制如抗拉强度及产品的金相组织和氧化铁皮厚度进行最终控制
计算机系统用于控轧和控冷无张力轧制最佳剪切尺寸控制和缺陷检测
本设计采用的工艺技术及选用的设备代表了当今世界上较为成熟的主流先进技术
Abstract
In this design a new single line high speed wire mill with the output of ton per year will be built This imum rolling speed reaches 120ms guarantee speed reaches 100ms The specification of the products fromφ55 toφ12mm diameter and each coil is about 2 ton
The billets are heated by mix coal gas in a controlled atmosphere walking-beam furnace which is controlled puter The heating capacity is 75thand its exit temperature is from 900℃~1050℃
The rolling mill adopts 120-mm sqare 12-m long and 13-ton weight billets which casted by continuation casting machineAfter 12 H-Vhorizontal roughing and intermediate standsa rod-wire process line are arranged This line consists of 4cantilevered prefinishing stands and a 8-stand Morgan No Twist finishing blockat lastfor guarantee its qualtity every wire though off a 4-stand Reducingsize Mill
Post-rolling cooling is achieved by water-cooling conveyor adopts tardy cooling device which carry final control of metallurgical properties such as tensile strength and scale thickness
puter system is used for controlled rolling and cooling no-tension rolling optimum cutting gage-controll and defect detection etc
The technology and fracilities this design stands for the prime advanced-technology nowadays
Keywords work-shop design wire mill high speed wire
